Every monarch inherits the mother of all art collections—one million items including 7,000 paintings, 30,000 watercolors, and half a million prints, to say nothing of sculpture, furniture, and jewelry—but the late Queen Elizabeth decided to show many of them to the public. Only a tiny fraction is here; the booty is also in palaces such as Kensington and Hampton Court, and on loan. The works you'll see here (budget 1 hr.) are undoubtedly exceptional (one of the world’s few Vermeers, a Rubens self-portrait given to Charles I, glittering ephemera by Fabergé), but depending on what temporary exhibition supplements them, they may not be the cream of what the crown owns, and it may bore kids. The Gallery also hosts regular temporary themed exhibitions.
